GAS-SAVER.

To all whom t may concern.'

Be it known that I, GEORGE EAGAR, a subject of the King of Great Britain, and a resident of Dunboyne,` in the county of Elgin, in the Province of Ontario, Canada, have invented a new and useful Gas-Saver, of which the following is aspeciiication.

This invention relates to gas savers and has particular relation to an apparatusor appliance adapted to 'be used in connection with explosive motors employing gasolene or other highly volatile fuel.

away, t

The primary object of the invention is to provide means for saving and utilizing the vapors which are given off by gasolene and the like by inducting. them to the exploslve chamber of the engine along with the explosive charge.

A practical embodiment of the invention is shown in thev accompanying drawings, and will be hereinafter described in detail, it being understood, however, that I do not limit myself to the specific embodiment of the invention herein shown, as various changes may be made in .practising the in vention,without departing from the spirlt or principle of same as herein shown and claimed. y

In the accompanying drawings,

Figure 1 is a view in side elevation of an internal combustion engine showing one form of application of my device thereto,

Fig. 2, is a view in section of the controlling valve for admitting the gasolene vapor to the manifold of the engine, and also in side elevation, partly broken e operating rod of the valve,

Fig. 3 is a horizontal sectional view taken on the line III- III of Fig. 2.

Fig. 4 is a sectional view of the vapor tube showing its attachment to the top of a gasolene tank, and

Fig. 5 is a top plan view o f the same.

To put my invention into practice, for instance, in connection with an internal combustion engine, I tap a nipple or short pipe as showing'l 110, into the manifold 11, of the engine, and

connect the threaded neck 12v of a valve body 14 with this nipple or -pipe 10. Obviously, the neck 12 can be attached directly into the manifold, but as this neck in theordinary valve is usually short, it is preferable to provide the nipple 10, in order to space the valve suiiiciently far away from the manifold to permit free operation of an operating mechanism. Into the neck 15 on the Specification. of Letters Patent.

Patented May 11, 1920.

Application led March 26, 1919. Serial No. 285,398.

opposite' side of the valve body, I thread a. short pipe 16 both ends of which are open, and which pipe intermediate its ends is rovided with a branch 17 extending at right vangles to the pipe 16. The valve body 14 is provided with an ordinary plu valve 18, the port 19 of which is brought into or out of registry with the passageway through the valve body by a suitable operating means.

Where the device is used with the engine of an automobile, it is desirable, of course, that the valve may be operated by the driver from a point convenient to his seat. A convenient and thoroughly practical means for so operating the valve is herein shown, and consists of a disk as 20, securely fixed on the stem 21, of the plug 18, and which disk is provided with a pair of openings as 21, which receive the forked ends or arms 22, of van operating rod 23 extending through the dash board of the automobile where it may be conveniently reached by the 0perator.

It is well known, that a considerable amountof vapor accumulates in the top of l'any tank of gasolene or` other highly explosive oils, and this vapor is ordinarily permitted to escape to the atmosphere. It is' my purpose to conserve this vapor and utilize the power units that the same may contain in the explosive charge. To this end, I provvide the gasolene tank as 24, withg an opening as 25, and over this openin 25 I aix securely to the tank,la plate 26 w ich is pro'-V vided with an upwardly extending tube 27,

fthe bore of the tube being restricted or of such size as to provide a relatively small opening leading to the opening 25. Afiixed to the plate 26 surrounding the tube 27 isthe leg 28 of an elbow-shaped pipe, to the other leg 29 of which is connected one end of a tube 30;- the other end of thistube is connected to the branch 17 of the pipe 16. The

outer end of the leg 28 is open as at 31,

I permitting the accumulating vapors to escape during the timev the engine is standing idle.

v The operation of the device will be at once apparent from the drawings taken with the foregoing description, as it will be observed that with the engine in operation, with the valve 18 fopen, a suction will be' created through the valve passageway and pipe 16, and through the fieXible tube 30 and tube 27, this sucking the vaporized gasolene from the top of theY gasolene tank and making use of the same to assist in the running 1. In combination with a gasolene tank having a vent opening, and the manifold of an internal combustion engine, a valve body secured to the manifold and having its passageway communicating with the manifold, a valve in said body, Voperating means vfor said valve, and connectionsl between the ventopening of the gasolene tank and said valve body. f

2. In combination' with a gasolene tank provided with an outlet for vapors generated in said tank, of a tube connected to the outlet, and a vvalve connected with the tube,.

and also connected with the manifold of an internal combustion engine, whereby the suction through the manifold will draw the vapors from the tank through the tube into the manifold of the engine. A

3. In combination, a tank having a vapor outlet in the top thereof, a tube connectedto the outlet, a valve to which the other end of said tube is connected, said valve'being in communication with the manifold of an internal combustion engine, and means for opening and closing said valve.

4. The combination with. the intake manifold of a gas engine, and fuel supply tank having a vent opening, of manually controlled means for forming communication between the manifold and vent opening.v

The combination with the intake manifold of a gas engine and a fuel supply tank provided with a vent opening, of means for forming communication between the vent opening and manifold.

6. In combination, a gas engine manifold, a fuel supply tank having an opening therein, a .vent tube associated with said opening, an elbow inclosing said tube and having an opening to the atmosphere, and pipe connections between said elbow and manifold.

7. In combination, a gas engine manifold, a fuel supply .tank having an opening therein, a vent tube associated with said opening, a valve-controlled pipe section connected to said manifold, and means for forming communication between said vent tube and pipeI section. y

8. In combination, a gas engine manifold. a fuel supplytank having'an opening therein, a vent tube associated with said opening. an elbow inclosing said vent tube and having an opening therein at the angle of the elbow with the outer end of the vent tube inl line therewith and means for forming communication between the elbow and manifold.

In testimony whereof, I have signed in the presence of the two undersigned witnesses.
